Is Diamond Fluorescence Good or Bad?

Over the years, there has been a growing misconception about the fluorescent property of diamonds, some regard it as a good feature while the others say it’s bad. Are diamonds fluorescence really bad like they say? Let’s take a while to make some observations and understand some interesting features of diamond fluorescence and why it should be considered a good feature. Let’s start with an in-depth understanding of its meaning.

What is Diamond Fluorescence?

This is a soft colored glow, a diamond usually gives off when exposed to ultraviolet rays like the sun, fluorescent bulbs, or night clubs (and any other UV light), after it undergoes electromagnetic radiation. It can also be seen as the diamonds reaction when exposed to radiation.

According to the Gemological Institute of America (GIA), the reactions from diamonds are being graded into 5 levels  – very strong, strong, medium, faint and none in a descending order, a well-trained eye can notice the difference in ordinary lighting while the faint eyes need UV lights to notice the different fluorescence levels.

What Causes Fluorescence in Diamonds?

Getting a diamond with no traces of chemical compounds, more like pure diamonds rarely occurs. When diamonds undergo the processing stage, some compounds are being absorbed, which causes the reaction to ultraviolet rays, the 3 main compounds include – aluminum, boron, and nitrogen. When a diamond fluoresces, it is said to contain one of these compounds.

What Colors Fluorescence Gives off to Diamonds?

There are different colors of diamonds fluorescence, it could either be a yellow, green, red, blue, orange or even white color (these are the common colors, and there are some others), but blue is the most common among them. These colors of diamond are usually noticed when exposed to ultraviolet rays.

The color diamonds give off is very important. Fluorescence gives effect to colorless or colorful diamonds. Blue fluorescence is the most common color a colorless diamond gives off. If it’s a yellow diamond the fluorescence won’t easily be noticed except when exposed to UV light and in most cases shines out extraordinarily.

What to Consider Before Purchasing a Diamond with Fluorescence?

This is one of the aspects that make diamond fluorescence a good option because it now depends on individual preferences, which is summarized using the 4Cs, let’s take a quick look on each:

Diamond Cut :This is the first c to consider, the cut of the diamond (some people mix it with shape), a well-cut diamond shows off an outstanding and beautiful property, while a poorly cut one will appear faint and dark. They could be cut in ideal shapes either round, hearts and arrows. The brilliance of the diamond is essential and can be portrayed through the cut.

Read about some other special cuts like JamesAllen True Hearts diamonds, or the recently featured Astor By Blue Nile in their dedicated review articles.

Diamond Color: Their colors are usually graded from D-Z, having a particular choice of color helps, they are either light, very light, faint, nearly colorless or colorless. For example, D-F is considered colorless, G-J nearly colorless, K has a faint color. Go for your preferred choice, but if you want an advice on how not to be “over-sold” to a higher color, read this.

Diamond Clarity: The diamond’s clarity should be considered, go for diamonds that are eye-clean, clear beautiful appearance and won’t disrupt other features of the diamond.

Diamond Carat (weight): Carat, formerly known as carob refers to the diamond’s weight. The weight size of your diamond should be your choice, and the cut will determine either light or heavy.

Asides the 4Cs, fluorescence has been added to things you need to consider. because it has a lot to do with the appearance of your diamond.

  • Avoid fluorescence with high color grades, G and above. They seem to make diamonds appear hazy, oily or milky.
  • Go for diamonds from H below, they have medium color grades, which enhances the appearance of your diamond.
  • You can say if a diamond is a fluorescence by yourself by simply having an upside-down view of it, under ultraviolet rays.
  • If you are buying a diamond with G-H color or better stay away from Medium and Strong fluorescence. You will not benefit at all from its presence but you may very well see some of the haziness.
  • If you are buying a diamond with H or lower color then you may benefit from a diamond with Medium fluorescence. I wouldn’t go so far as to recommend Strong Blue as in this case the benefit of the color improvement is outweighed by the haziness
